3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Overload capability Characterizing the variable frequency speed control equipment, under the specified working conditions, can output more than the rated current within the specified time period without protection. ability. Note 1. The frequency conversion speed control equipment for metallurgy is generally expressed in the form of a cycle. The manufacturer has to give a multiple that exceeds the rated current during this period. The time and the multiple of the relative rated current is not exceeded. During this period, the larger the part exceeding the rated output current, the longer the duration, The stronger the carrying capacity. Note 2. Rewrite GB/T 12668.1-2002, definition 2.5.3. 3.2 Harmonic component harmoniccomponent Any component with a harmonic frequency. The value of the harmonic component is usually expressed as a rms value. [GB/T 12668.3-2012, definition B.2.2.4] Note. For the sake of simplicity, this component can be simply referred to as harmonics. ...
